Review the sites of Analog Devices, Microchip, Linear Technologies for the ADCs they offer - these (16+ bit) ADCs typically include a drawing in the data sheet on how to use these chips with a Wheatstone bridge - especially when you're dealing with very high-resolution ADCs like the LTC2485, for example.

Theoretically, you could also use an op-amp with an Arduino to build a crude wheatstone bridge. However, I wouldn't simply because the resolution of the ADC inside the Arduino isn't that great (about 10 bits).
